    Hi guys,

    We have discovered a small, but annoying bug in RadMultiPage in Q1 2010 release (version 2010.1.309).

    A JavaScript error can occur when using the debug versions of the MS AJAX library (<compilation debug="true"> in web.config).

    There are three solutions, please pick one of them:

    1. Set ScriptMode="Release" property of the ScriptManager / RadScriptManager.

    2. Disable the debugging in the web.config file:
        <compilation debug="false">

    3. Override the dispose method of the control on the page:
    <asp:ScriptManager ID="ScriptManager" runat="server">  
    <script type="text/javascript">  
        (function() {  
            var oldDispose = Telerik.Web.UI.RadMultiPage.prototype.dispose;  
            Telerik.Web.UI.RadMultiPage.prototype.dispose = function()  

    What is Next
    The problem is already fixed and will be available in the next Latest Internal Build and the first service pack.

    We apologize for the caused inconvenience.
